Effects of growth hormone-releasing hormone deficiency in mice beyond growth.

This paper provides a critical overview on GHRH and its deficiency, discussing its multiple roles in both central and peripheral tissues. Genetically engineered mice have been instrumental in elucidating the multifaceted roles of GHRH and GH, each offering unique insights into the physiological and pathological roles of these hormones, although in many of these models dissecting the direct effect of GHRH from the effect of GH is not possible. Key findings highlight the effects of GHRH deficiency on emotional behavior, including anxiety and depression, its impact on memory and learning capabilities, as well as on adipose tissue, immune system, inflammation and pain.
